5.1 surround sound placement

[nugget2014]

in my room placement is limited, at the moment my surround placement is bad, i am hoping to have this changed. if i was to have my surround right speaker up at the top of the wall but firing down a bit towards me, would that work alright? then it would be at the side of me instead of 2 foot ahead of the listening area.

picture seems to have rotated, should still be able to see proprly though,

It must be very limited if you have to hang the settee on the wall*biggrin*

but seriously to answer your question, yes it would be better to mount your rear spk so that it will be in line or behind your listening position, no way should it be forward (and especialy not two feet ahead).

Yes, in my previous house, the rear speakers were up close to the ceiling pointing towards the seating position. Worked fab. Try to get it in line, instead of 2 feet forward.

Thanks. I'll see what's possible when I have quote for installation of everything.

Having the surround speakers at the side of me might help me pinpoint the sound better and hear it. But the surround back still has the issue of me not hearing any sounds from there at all.

What would you suggest for the surround back speakers? I was going to replace them with zensor pico so i could boost the db level without distortion but maybe proper positioning would solve that problem without upgrading?

Would having the minx for surrounds and pico for surround back be a bad idea?

I dont want the problem of having the minx speakers installed then the back ones still dont produce enough volume for me to hear them.

Or the other option is selling two of my speakers use the other two as surrounds and eventually buy the kef upfiring atmos speakers in a 7.1.2 setup.

Have you Checked the levels of your speakers to confirm they are equal?

Why not boost the rear channels by +0.5 or 1db until you are happier with the balance.

Costs nothing to do this

I have done. Even at plus 10 cant hear it

Heard back from CA the min11s go to 85db while the monitor audio radius 45s i was looking at go to 101. So should be a nice upgrade. Going to go down to 5.1 for a few reasons

I can hear the surround speakers now just not the rears so having better surrounds will only improve the setup more along with installation. And eventually i will get upfiring kef atmos speakers!

In my size room and especially since moving setup to opposite side 7.1 doesn't make much sense.

One other thing to look at is your distance setting to the rear speakers

I would try reducing that in the av receiver as well as the timing might be out with the rest.

Why are you buying different manufacturer speakers to dali.
Ideally you want it all the same.

The zensor pico wont fit in the small area i have above the patio door. Only tiny speakers will thats why im going for the radius 45 and going down to 5.1

Only location for my surround right is above the door so it has to fit.

Although Radius speakers are very good (I had them in my previous house - R225HD and R90HD), don't expect miracles from such tiny speakers. It's the law of Physics.

i dont need a miracle, i just need more maximum volume so they don't distort/pop. besides, there's no other speaker that is better that can fit above that patio door.

 

[nugget2014]

I want to go 5.1 for sure but the advisor at richer sounds keeps telling me i am wrong and 5.1 is having surround back speakers without surround rears. This isnt the case and anyway why would my av receiver not allow to me use that if he was right?

He is saying i wont notice any benefit with the radius over the minx speakers in my setup and he said so because of the speaker wattages. So he thinks the speaker wattage is the determining factor?

I can't win.

Is he right or am i? In a 5.1 setup do you have surround speakers or surround back speakers??

 

[ellisdj]

Surround speakers to the side for 5.1

Surround backs are for 7.1

You are right.

What speakers are you not hearing at the minute??

I thought it was the backs

indeed, it is the backs, when i went in for 15 mins to try and get a quote sorted and buy the speakers i ended up walking away with nothing as most of the time was spent telling me one thing which is wrong regarding what i mentioned the speaker positioning.

upgrading my minx to the radius 45's should be a decent upgrade in terms of max volume, and when they are level to the ears not 2 feet in front like at the moment they will sound even better still. and 3-6 months down the line i will add upfiring kef atmos speakers.

hopefully tomorrow i will have it sorted..then i have the problem of choosing between svs and arendal sub as i can now buy it after receiving my backdated money i was on about for months!

would the arendal sub 1 be good enough for movies? watching batman v superman is a struggle with my sub, feels like it cant cope with the demanding ULF

 

[nugget2014]

I've bought the radius 45s and having a quote on Saturday for installation.

Full steam ahead!

Hi Nugget2014

As promised please see below for some useful links to resources which can be used to help calculate multiple subwoofer positions, speaker positions, room modes etc etc. Properly applied this information should assist you on your quest for audio and video nirvana.

Room mode calculator (basic) - http://www.harman.com/download/file/fid/2156

Room resonance (advanced) - http://www.harman.com/download/file/fid/2141

Multi sub positioning

If you get serious and want to sort out your room acoustics, here is a nice analitics app from the fellows at Artnovion. http://www.artnovion.com/impulso-app (needs to be used with an iPad ideally) - you use this app and the resulting file combined with a scale drawing of your room, fixtures, fittings and funiture positions and type to send to artnovion who, for a small fee, will run full diagnostics of your room and recommend suitable absorbsion, diffusion and reflection panels.

Finally.

Here is the link to the Dolby white paper I mentioned on speaker placement for Atmos.

http://www.dolby.com/us/en/technologies/dolby-atmos/dolby-atmos-home-theater-installation-guidelines.pdf

Please note the rears are depicted behind the listener (slightly) although can be as far forward as level with the listener. please also note the speakers are all on the same plane (i.e. not elevated).

In you room I would be a little concerned that the rear right speaker would be placed too high (over the window) and the separation for the height channels in Dolbly Atmos would be missed. This combined with the fact the rear left is at ear level could produce some very weird effects. It may be more worthwhile investing in some speaker stands for your side speakers so they are at least at the same height and so they can be repositioned for best effect depending on how they interact with the environment. This should (long term) assit with Dolby Atmos overhead speakers becoming more effective.

With respect to your viewing distance I found this tool to be very useful in the past.... Note that it shows pixels per degree not pixel per inch. It also references the documentation to back up its calculations. Of course other rules will apply regarding seating distance from screen and field of view, but I find this is a great starting point to make sure you are getting the benefit of any given resolution screen at any given distance.

Good luck with your project.
